Story summary

Researchers have uncovered that Purkinje cells in the cerebellum play a crucial role in controlling tongue movement in marmosets, signaling when to halt as the tongue approaches its target. Disabling these cells resulted in erratic tongue movements, underscoring the cerebellum's vital function in fine motor control and offering potential pathways for treating speech and swallowing disorders.
